- Comprehensive AC Oil Dye Injector Kit : This essential kit includes a 2 oz Oil Cylinder, R134A low side quick coupler (1/4'' SAE male x 13mm female), Blue Low side R1234yf coupler (14 mm female x 1/4'' SAE male), R410a mini split adapter (5/16'' SAE Female to 1/4'' SAE Male), and a Dual Head Valve Core Remover, ensuring compatibility with R134A, R12, R410A, and R22 AC systems. - Professional Field Tool : Made with a durable aluminum alloy body, this 2 oz push-in type refrigerant injector doesn't rely on a working compressor to inject oil or fluorescent dye into the system. It can effectively rejuvenate a compressor suffering from low oil levels, making it suitable for R410A, R134A, R22, and R12 refrigerant systems. - Heavy-Duty Design : The R410a mini split adapter, R1234yf low side pressure adapter, and R134a low side pressure adapter are constructed from robust brass. This guarantees long-lasting performance. The kit allows for seamless integration with fluorescent dyes for leak detection and is compatible with all oil types (POE and mineral) across both automotive and home AC systems. - User-Friendly Operation : Utilizing the 2 oz hand-turn dye and oil injector is straightforward. Simply screw the check valve onto the cartridge, tighten the inner and outer cylinders clockwise, and use the 1/4 SAE threaded inner core to purge a small amount of air. Connect the injector to the low-pressure port of the refrigeration system to add the necessary cooling oil easily. - Practical Applications : - Use this kit for routine maintenance of car air conditioning systems to ensure optimal performance. - Ideal for HVAC technicians performing servicing and repairs on commercial and residential AC units, enhancing operational efficiency. - Perfect for diagnosing leaks in AC systems using fluorescent dye, ensuring timely and effective repairs.
